The roofing material is pressed against the cant by aflashing strip which has the free end extending upward in sea]- ingcontact with the inner surface of the reglet. The reglet is of channelsection having a recess facing outwardly with the top and bottom flangesconverging at a substantial angle. The cant is a strip mounted at anangle to the wall and roof deck with a vertical flange at the topextending into the reglet and with a horizontal or vertical flange atthe bottom which is nailed or otherwise secured to the roof deck. Themarginal portion of the roofing material extends upwardly over the cantto within the reglet and a flashing strip which is preferably resilientand so formed as to compress the felt layers of the roof materialagainst the cant is secured thereby by spaced screws. The extending edgeof the flashing strip is forced upwardly against the inner surface ofthe downwardly extending top flange of the reglet in sealed relationtherewith. The screws secure the flashing strip to the felt layers andcant and the layers are compressed forwardly of the screws to retain theroofing material from movement relative to the cant.

Where the reglet is extruded as a unit with the coping, the parapet orwall is provided at the top with a treated wood member which permits theunit to be nailed, screwed or otherwise secured thereto. In another formof the invention, the reglet may be a part of an extrusion which isnailed or otherwise secured to the roofdeck and which is provided at thetop with an extending portion having a detent therealong over which adetent on a flange at the inner edge of the coping interlocks whenforced thereover. Where the parapet or wall is substantially higher thanthe location of the reglet, the extending portion with the detentthereon may project upwardly to near the top of the parapet or wall soas to be in position to support the coping over the top thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, a roofdeck 11 is enclosed by an upwardly extending parapet 12 which may varysubstantially in thicknesses. The top run 13 of the parapet is hereinillustrated as being made of treated wood, which is secured to the toprow of bricks 14 in an acceptable manner, herein illustrated as by bolts15 having a plate 16 at one end secured in the mortar 17 between thebricks. The bolts extend through apertures 10 in the run 13 and areprovided with a threaded end 18 which locks the wood run to the top rowof bricks 14 when secured by nuts 19 located within recesses 21 at theend of the apertures 10.

The coping unit 22 has a sloping top section 23, a front side section 24and a rear side section 25 with the side sections disposed in parallelrelation. The section 25 has a downwardly sloping flange 26 near the topand an upwardly sloping flange 27 at. the bottom forming a reglet 30 towhich the roof material 28 is sealed. The rear side section 25 issecured to the wood run 13 by screws 29 and the front side section 24 isprovided with an inwardly extending flange 31 which rests upon the run13. The side section 24 may be secured to the run 13 by screws orotherwise but is herein illustrated as having the bottom edge deflectedoutwardly at the bottom and reversely bent to form an upwardly slopingchannel 33. A securing strip 34 is nailed to the run 13 in position tohave an angularly extending flange 32 project into the channel 33 forsecuring the front side section 24 against upward movement.

A cant 35 slopes from the parapet to the deck and is provided with adownwardly directed vertical flange 36 at the top which extends over theupwardly sloping flange 27 at the bottom of the reglet. The bottom endof the cant has a horizontal flange 37 which is secured by nails 38 tothe roof deck 11. A plurality of layers of roofing material 28 extendsfrom "the roof deck upward over the cant into the recess 40 of thereglet with the layers secured to the cant by a flexible flashing strip39.

The flashing strip 39 has a forward concave portion 41 extending from anangularly disposed flange 42 from which a flange 43 extends outwardlyalong the edge. Holes are provided through the angular portion 42through which screws 44 with neoprene sealing washers 45 under the headsare driven into punched holes in the roofing material 28 and the cant 35to force the flashing strip 39 into firm engagement with the roofmaterial along the line 46. This forces the concave portion 41 of theflashing strip 39 upwardly to have the extending edge engaged and sealthe inner surface of the top sloping flange 26 of the reglet.

A similar construction is illustrated in FIGS. 2 and 3 wherein a reglet51 is supported on the upper end of a strip 52 having a horizontalflange 53 which is secured to the roof deck 1 l-by a plurality of nails54. The reglet supports the cant 35, roofing material 28 and theflashing strip 39 in the manner described above with regard to theconstruction of FIG. 1. The reglet has an extending section 55 along thetop edge with sloping lateral projections which form detents 56 one ofwhich is engaged by a detent 57 on one of a pair of spaced flanges 58and 59. The downwardly spaced flanges 58 and 59 retain the detents ininterlocked relation. The outer flange 59 is extended to cover thedownwardly directed flange 26 of the reglet and the spaced edges ofadjoining flanges 26. The flanges 58 form the inner side wall of thecoping 50 which is otherwise the same as the coping 22 of the structureillustrated in FIG. 1. The advantage of this construction resides in thefact that the section 55 may extend upwardly any desired amount so thatit will be adjacent to the top run of the parapet or wall when thelatter is built to a height above the roof deck substantially greaterthan that herein illustrated.

Referring to FIGS. 4 and 5, a further form of coping is illustratedwhich is similar to that shown in FIG. 1 but which is applied to a wallsection which embodies a wood extension 60 and a front face section 61.The front face section 61 herein illustrated is made from a sheet ofmetal which has flat sections 62 and angular sections 63 which may be inunit relation to the flat sections or may be angular elements whichinterlock therewith. In place of the metal front face section 61, asection may be built up from concrete having stones or other elementsembedded therein to form the face section. The flat section 62 of theunit 61 is secured to the wood wall extension 60 by nails 64. A copingunit is herein illustrated as being an extruded section having ahorizontal top flange 65, a downwardly extending front flange 66 and adownwardly extending rear flange 67 which is formed into a reglet 68.The reglet has a web section 69 which is in extension of the flange 67and upwardly sloping bottom flange 71 and a downwardly sloping topflange 72 providing a recess 73 therebetween. The cant 35 has its topflange 36 supported within the bottom flange 71 of the reglet over whichthe roofing material 28 is supported and sealed against the cant 35 bythe application of the flashing strip 39 in the manner pointed outhereinabove. The web section 69 of the reglet 68 has apertures 74 spacedtherealong through which screws 75 are driven into the wood extension 60of the wall section. The screws support the coping over the top edge ofthe wall section which supports the reglet 68, the cant 35, the roofingmaterial 28 and the flashing strip 39 in firm fixed, sealed relation toeach other and the wall section.

In FIG. 6, a further form of coping is illustrated which is similar tothat illustrated in FIG. 2. In this construction, the coping element 76has a sloping top web 77 and a vertically disposed front face 78. Theweb on the inner end has a downwardly extending flange section 79 and onthe inner face a downwardly and inwardly extending flange section 81 onthe forward edge of which a sloping detent 82 is provided. The frontdownwardly extending face 78 has an inwardly directed flange 83 whichrests upon the top run of the wall 80 to space the forward edge of thetop web 77 a substantial distance thereabove. A reglet unit 84 has avertically extending web 85 and upwardly extending bottom flange 86 anda downwardly extending top flange 87 with an outwardly facing recess 88therebetween. A flange 89 slopes upwardly and forwardly from the top ofthe reglet 84 and is provided with a sloping detent 91 along the outeredge. An offset locking strip 92 is secured to the top wood run 93 by aplurality of nails 94. The reglet is provided with spaced apertures 95in the vertical web 85 through which screws 96 extend into the wood run93 for securing the reglet on the inner face of the run. After thereglet has been secured in this manner by the screws 96, the copingelement 76 has its forward end raised so that the rearward end includingthe flange section 79 can be slid over the top of the reglet to have thedetent 91 engage the detent 82 after which the coping element is moveddown and further slid toward the reglet to have the detents 82 and 91interlock and the flange 83 advanced beneath the extending flange 97 ofthe securing strip 92 to thereby lock the coping element to the regletand the top of the wall. The cant 35, the roofing material 28 and theflashing strip 39 are applied in the same manner as pointed outhereinabove with regards to the other Figures. In all of thearrangements the reglet supports the cant, roof material and flashingstrip in fixed sealed relation and provides the main support for thecoping portion associated therewith.
